The industry was in its infancy and the concept of creating and maintaining clean and contamination free environments was alien to many industries. Major pharmaceutical, research, electronic component manufacturers, military and government agencies were just some of a cross section of customers we have serviced. Starting essentially as a distributor of products for the last 20 years, the transition to design and manufacture was a giant leap for the company. In the early 90's, with the advent and resurgence of TB, the company took a different approach and direction in designing and building equipment specifically for airborne infection control applications. The first product to be developed was our MICROCON 800 air purification system.
